摘要
高速公路可变限速控制的基本原理,根据能见度距离及路面附着力系数计算不同气象条件下允许的高速公路上的最大行车速度。设计开发基于GSM模块的电子限速牌的远程数据无线收发系统,实现高速公路沿线电子限速牌的远程控制,达到对高速公路主线交通流进行速度控制的目的。
The basic principle of highway variable speed-limit control is introduced. The allowed maximum driving speed on freeway in different weather conditions is calculated according to the visibility distance and road surface adhesion coefficient. A remote data wireless transceiver system of speed limit electronic board is designed and developed based on GSM module in order to achieve the remote control of speed limit electronic board along the roads, and to complete the speed control purposes for main traffic flow on highway.
